This prevents an attacker from spoofing argv[0] to bypass apparmor restrictions.
- `env -a false ls` now correctly runs `ls` instead of dispatching as `false`
- Also works under masked `/proc` (does not rely on /proc/self/exe).
Closes#10135
* ls: fall back to "." metadata for ".." on WASI
On WASI the sandbox blocks access to the parent directory at the
preopened root, causing ls -a to show an error and display ".."
with question marks. Fall back to the current directory metadata
so the entry appears with valid information.
`signal_by_name_or_value()` only looked up signals from the static
ALL_SIGNALS array, which doesn't include realtime signals. This caused
`timeout -s RTMAX`, `kill -s RTMIN`, and `env --default-signal=RTMAX`
to reject valid signal names.
Extend the function to fall back to realtime_signal_bounds() for both
name lookups and numeric values in the realtime range, matching the
behavior already present in signal_list_value_by_name_or_number().
Also fix timeout's report_if_verbose() to use signal_list_name_by_value
instead of signal_name_by_value, so verbose output doesn't panic for
realtime signal numbers.

Some distributions have already adopted uutils as `/bin/ls`. Continuing
to compare against the binary at that path would only result in
comparing against a much older uutils version and fail to compare
against GNU Coreutils at all. Ubuntu 25.10 has prefixed GNU's binaries
with "gnu", so mention this to retain the intended behavior.
There was quite a bunch of different features missing in timeout, to start off, now that we have a mechanism to read the SIGPIPE handlers before they are overwritten by the rust runtime, it means that we can not propagate this signal down to the child processes if the signal is set to ignore.
This also includes all of the latest changes since 9.9 where the specific signal sent to timeout will be propagated instead of just defaulting to a TERM signal.
Implements era year calculation for Buddhist, Persian Solar Hijri, and Ethiopian calendars based on locale detection. The %Y format specifier now outputs era-appropriate years while maintaining Gregorian calendar for ISO-8601 and RFC-3339 formats for interoperability.
This adds a new option to get reproducible output from a seed. This
was already possible with --random-source, but doing that properly was
tricky and had poor performance.
Adding this option implies a commitment to keep using the exact same
algorithms in the future. For that reason we only use third-party
libraries for well-known algorithms and implement our own
distributions on top of that.
-----
As a teenager on King's Day I once used `shuf` for divination. People
paid €0.50 to enter a cramped tent and sat down next to me behind an
old netbook. I would ask their name and their sun sign and pipe this
information into `shuf --random-source=/dev/stdin`, which selected
pseudo-random dictionary words and `tee`d them into `espeak`.
If someone's name was too short `shuf` crashed with an end of file
error. --random-seed would have worked better.
When the --random-source option is used uutils shuf now gives
identical output to GNU shuf in many (but not all) cases. This is
helpful to users who use it to get deterministic output, e.g. by
combining it with `openssl` as suggested in the GNU info pages.
I reverse engineered the algorithm from GNU shuf's output. There may
be bugs.
Other modes of shuffling still use `rand`'s `ThreadRng`, though they
now sample a uniform distribution directly without going through the
slice helper trait.
Additionally, switch from `usize` to `u64` for `--input-range` and
`--head-count`. This way the same range of numbers can be generated on
32-bit platforms as on 64-bit platforms.
This gives a 1.8× speedup over a stdlib formatted write for
`shuf -r -n1000000 -i1-1024`.
The original version of this commit replaced a formatted write, but
before it got merged main received optimized manual formatting from
another PR. The speedup of itoa over the manual write is around 1.1×,
much less dramatic.

* stty: Add 101 unit tests and 16 integration tests to improve coverage
Add comprehensive test coverage for stty:
Unit tests (src/uu/stty/src/stty.rs):
- Flag struct methods and builder pattern (7 tests)
- Control character parsing and formatting (19 tests)
- All combination settings expansion (26 tests)
- Termios modification functions (13 tests)
- String-to-flag/combo/baud parsing (19 tests)
- TermiosFlag trait implementations (5 tests)

- Control character overflow validation (2 tests)
- Grouped flag removal validation (1 test)
- File argument error handling (1 test)
- Conflicting print modes (1 test)
- Additional TTY-dependent tests (6 tests, ignored in CI)
Unit test coverage improved from 0% to 43.76% (207/473 lines).
Integration tests validate argument parsing and error handling.
Addresses #9061
* stty: Add essential unit tests and integration tests to improve coverage
- Added 11 essential unit tests for complex internal functions:
* Control character parsing (string_to_control_char)
* Control character formatting (control_char_to_string)
* Combination settings expansion (combo_to_flags)
* Terminal size parsing with overflow handling (parse_rows_cols)
* Sane control character defaults (get_sane_control_char)
- Added 16 integration tests for command behavior:
* Help/version output validation
* Invalid argument handling
* Control character overflow validation
* Grouped flag removal validation
* File argument error handling
* Conflicting print modes
* TTY-dependent tests (marked as ignored for CI)
Unit tests focus on complex parsing logic that's difficult to test via
integration tests. Integration tests validate actual command behavior.
Coverage improved from 0% to 43.76% (207/473 lines).
Fixes#9061
* stty: Add comprehensive unit and integration tests for error handling
- Add unit tests for parse_rows_cols() with edge cases and wraparound
- Add unit tests for string_to_baud() with platform-specific handling
- Add unit tests for string_to_combo() with all combo modes
- Add 17 integration tests for missing arguments and invalid inputs
- Enhance test_invalid_arg() with better error message assertions
- Update coverage script for improved reporting
Coverage improved from 22.26% to 23.14% regions.
* stty: Add Debug and PartialEq derives for test assertions
- Add #[derive(Debug, PartialEq)] to AllFlags enum
- Add PartialEq to Flag struct derives
- Enables assert_eq! macro usage in unit tests
* stty: Fix formatting and clippy warnings in tests
- Replace assert_eq! with assert! for boolean comparisons
- Fix line wrapping for long logical expressions
- Use inline format string syntax (e.g., {err} instead of {})
- All 25 unit tests pass
- No clippy warnings
* stty: Add inline spell-checker ignores for test strings
- Add spell-checker:ignore comments for test data (notachar, notabaud, susp)
- Add spell-checker:ignore comments for French error strings (Valeur, entier, invalide)
- Fixes cspell validation without modifying global config
* perf: gate PartialEq derive to test builds only
The PartialEq derive was being compiled into release builds even though
it's only used in test code. This caused a 3.33% performance regression
in the du_human_balanced_tree benchmark due to increased binary size
affecting CPU cache efficiency.
Changes:
- stty.rs: Gate PartialEq derive on Flag<T> with #[cfg_attr(test, derive(PartialEq))]
- flags.rs: Gate PartialEq derive on AllFlags enum with #[cfg_attr(test, derive(PartialEq))]
This eliminates the performance regression while keeping all test code
functional and unchanged.

Implement locale-aware 12-hour vs 24-hour time formatting that respects
LC_TIME environment variable preferences, matching GNU coreutils 9.9 behavior.
- Add locale.rs module with nl_langinfo() FFI for POSIX locale queries
- Detect locale hour format preference (12-hour vs 24-hour)
- Use OnceLock caching for performance (99% faster on repeated calls)
- Update default format to use locale-aware formatting
- Add integration tests for C and en_US locales
Fixes compatibility with GNU coreutils date-locale-hour.sh test.
* feat: Add support for long double floating-point numbers and refine general float formatting.
* feat: Enhance `od` error reporting for file I/O, width, and offset parsing, including overflow detection and input validation.
* feat: Improve long double parsing by converting f128 to f64, enhance overflow error reporting with `libc::ERANGE`, and prevent final offset printing on input errors.
* style: Apply minor formatting adjustments across the `od` module.
* refactor: simplify float formatting logic and update string handling syntax
* fix: Correct float formatting logic to use decimal for numbers within range and exponential otherwise.
* refactor(test): use helper function in test_calculate_alignment
Replace repetitive assert_eq! calls with a new assert_alignment helper
to improve test readability and reduce code duplication. The helper
encapsulates alignment checks for OutputInfo::calculate_alignment,
making tests clearer and easier to maintain.
* feat(cspell): add ERANGE to jargon wordlist
Added "ERANGE" to the dictionary to prevent spell checker flagging it as a misspelling, as it's a valid errno constant from C libraries.
* feat(od): improve width error handling and subnormal float output
Refactor width option parsing in OdOptions to use i18n-compatible error messages via translate! macro, consolidating redundant error branches for better maintainability. Enhance float formatting for f16 and bf16 by introducing format_binary16_like helper to properly display subnormal values with exponential notation, removing the obsolete format_float_simple function and adding subnormal detection functions for accurate representation in od's output.
* refactor(od): simplify format_item_bf16 by removing redundant variable
Remove unnecessary `value` variable in `format_item_bf16` function, eliminating
a redundant cast and inline `f` directly for clarity and minor efficiency gain.
* fix(od): standardize option names in error messages
Remove hardcoded "--" prefixes from localization strings in en-US.ftl and fr-FR.ftl, replacing with a computed display name that includes "--" and optionally the short form (e.g., "--option" or "--option, -s"). Update parse_bytes_option and read_bytes functions to pass an option_display_name, enabling consistent error message formatting across localizations. Add validation to reject zero width values as invalid arguments. Improves user experience by providing clearer, more consistent option references in error outputs.
* refactor: condense format! macro in format_item_bf16 for readability
Removed unnecessary line breaks in the format! expression, keeping the code more concise while maintaining functionality. This improves code style in the float printing module.
* fix(od): add external quoting for filenames in error messages
The MultifileReader now uses `fname.maybe_quote().external(true)` when displaying permission and I/O errors, ensuring filenames are properly quoted for user-facing output (e.g., handling special characters that might confuse shells). This prevents potential issues with filename display in error logs.
* refactor(od): Rename f128_to_f64 to u128_to_f64 for clarity
Renamed the function in input_decoder.rs from f128_to_f64 to u128_to_f64
to accurately reflect its purpose of converting u128 integer bits to f64,
improving code readability and reducing potential confusion over float types.
* refactor(od): simplify error handling in OdOptions using combinators
Use map_err and the try operator to replace a verbose match statement,
making the code more concise and idiomatic Rust. This improves readability
without altering functionality.

* refactor(od): remove leaking from translated error messages in parse_offset_operand
Eliminated use of `.leak()` and unnecessary `.to_string()` calls on translated error strings in the `parse_offset_operand` function. This simplifies error handling, improves memory safety by avoiding intentional leaks, and makes the code cleaner without functional changes.

Add shared CPU hardware capability detection in uucore to prevent
code duplication across utilities. This provides a unified interface
for detecting CPU features (AVX512, AVX2, PCLMUL, SSE2, ASIMD) and
respecting GLIBC_TUNABLES environment variable.
This unblocks PR #9088 (cksum --debug) and PR #9144 (wc --debug) by
providing a common implementation that both utilities can use.
Features:
- CPU feature detection with caching (singleton pattern)
- GLIBC_TUNABLES parsing for hwcaps restrictions
- Cross-platform support (x86/x86_64, aarch64)
- Comprehensive test coverage
- Zero-cost abstractions using std::arch
Implementation details:
- Uses std::arch feature detection (no external deps for detection)
- Adds cfg-if dependency for conditional compilation
- Feature-gated behind "hardware" feature flag
- Android excluded (no CPUID access in sandboxed environment)
Related: #9088, #9144
* fix: handle EINTR (signal interruptions) in cat, od, and comm
Add proper retry loops for ErrorKind::Interrupted in I/O operations
to handle signals like SIGUSR1 that can interrupt read/write calls.
This pattern is proven in production - identical to PR #6025 (merged
March 2024) which fixed dd's EINTR handling for GNU test dd/stats.sh.
The same pattern is already used in 9+ utilities (head, tail, tee, wc,
sort, sum, tr, shuf, dd) without issues.
Changes:
- cat: Fix write_fast() and write_lines() to retry on EINTR
- od: Fix PartialReader::read() in all three read paths
- comm: Fix are_files_identical() for both file readers
- tests: Add InterruptingReader/Writer test utilities
Historical context:
- Pattern validated by cre4ture's PR #6025 (dd EINTR fix)
- Matches existing implementations in dd/dd.rs:450,881
- POSIX best practice for signal-interrupted I/O
Fixes#1275

* test: fix EINTR integration test failures
- Fix comm test: use stdout_contains instead of stdout_only for tabbed output
- Fix od test: create new command instance to avoid 'already run this UCommand' error
- Remove unused imports and dead code to eliminate compiler warnings
- Both tests now pass without warnings or errors
* style: fix formatting and remove duplicate comment in od test
* ci: add EINTR and related technical terms to appropriate cspell dictionaries
- Add EINTR, eintr, nextest to jargon.wordlist.txt (technical/systems programming terms)
- Add SIGUSR, SIGINT, etc. to shell.wordlist.txt (POSIX signals)
- Add uutils, coreutils, ucmd, etc. to workspace.wordlist.txt (project-specific terms)
- Fixes CI cspell warnings for legitimate technical terminology
- Proper categorization follows existing dictionary structure
